Two beakers are placed in a small closed container at 25 °C. One contains 284 mL of a 0.296 M aqueous solution of C6H12O6; the second contains 446 mL of a 0.103 M aqueous solution of C6H12O6. Small amounts of water evaporate from both solutions. As time passes, the volume of solution in the second beaker gradually and that in the first gradually . If we wait long enough, what will the final volumes and concentrations be?
